Re: [Crawl-ref-discuss] Removal of mechanical traps

[Matt L. <sav...@ho...>]

Dex could be used to find traps (or perhaps give a higher chance to "dodge" the trap - ie discover by stepping on, but not trigger) - as it's traditionally the "thief" class, but perhaps the other stats ought to have similarly fringe benefits (strength already ties in to armour and carry weight i believe doesn't it? perhaps int could have some effect on skill training?)
